Electrostrictive Multilayer PMN Actuators

PMN vs. PZT creep comparison

Our precision actuation capabilities continue to expand. For our Deformable Mirrors, AOA Xinetics has long supplied actuators made of Lead-Magnesium-Niobate (PMN). PMN actuators are similar to piezoelectric transducers (PZTs), but offer negligible hysteresis and creep, and approximately three times the stiffness for a given volume of material.
